ROBERT W. IRWIN, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO THE GRAND RAPIDS FURNITURE CO., A CORPORATION OF MICHIGAN.

FURNITURE-STANDARD.

Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed July 28,1906. Serial No. 328,229.

To all whom it may concern:

Be it known that I, ROBERT W. IRw'rN, a citizen of the United States, residing at Grand Rapids, Michigan, have invented certain new and useful Improvements in Furniture-Standards, of which the following is a specification.

My invention relates to improvements in furniture standards and is designed more especially for opera and like seats.

In devising my improved construction, I have aimed to provide a simple, strong and durable standard, capable of use with slight modifications as to dimensions for opera and school seats and desks. I have further aimed to provide a construction which, when embodied in an opera or like chair permits of a series of the chairs being arranged in a circle, or in a straight row, as desired.

With these and other objects in view the invention includes the novel features of construction and arrange ment and combination of parts hereinafter described and particularly pointed out in the claims hereunto appended.

The invention is illustrated in the accompanying drawing, in which,

Figure 1 is a side elevation of the standard as embodied in an opera chair. Fig. 2 is a plan view. Fig. 3 is a central vertical section taken along the line of the vertical bar 12, the central and lower parts being broken away so as to enable the view to occupy less space, while Fig. 3 is a sectional view along the horizontal dotted line shown in Fig. 1 looking downward upon the parts shown below.

Referring by reference characters to this drawing, the numerals 7 and 8 represent uprights or standards which are parallel for the greater portion of their length, one or both of them being as desired curved or bent outwardly at the bottom to afford a broader base or support. These standards are formed as shown of '1 iron with the central webs '7 and 8 facing each other and connected by cross pieces 9 of angle iron which are placed on opposite sides of the webs 7 and 8 and secured by bolts 10 fastened through both cross pieces and the webs as shown. If only one of the standards is curved outwardly at its lower end as shown in Fig. 1, the central web of this is cut away as indicated at 8 and the transverse part 8' of the T iron bent so as to rest fiat upon the floor and provided with holes 8 for the reception of screws.

For securing the lower end of the straight standard to the floor, I provide L shaped foot brackets 11 which are riveted or otherwise secured to the opposite sides of the web at its lower end and have their laterally ex tending ends provided with holes for the reception of screws.

The seat arms, and back are carried by the vertically extending bars 12 which have angularly bent ends 12 which are pivotally secured to the horizontal parts of the upper and lower cross pieces 9. This pivoted connection is preferably one which is capable of adjustment, that is, one which permits the vertical bar to be adjusted laterally upon the horizontal flanges whereby wider or narrower seats may be used without disturbing the arrangement of the standards. A convenient way of forming such an adjustable pivot is to provide a plurality of holes in one of the parts as shown and a single hole in the other part with removable pivoted bolts 13 fastened therethrough.

The seat arms 14 are each pivotally mounted upon a sheet metal bracket riveted to the pivoted upright and the back is supported by sheet metal brackets 15 riveted or otherwise secured to the upright bar above the seat bracket and it will readily be seen that by pivot ing the bars which support the seat and back in the manner shown, the seats may be set in a straight row or on any desired curve without necessitating any alteration in the shape of the parts they being all made of a standard size and shape and adjusted to suit the requirementsof the particular room where they are to be used.

Having thus described my invention, what I claim is:

1. In combination, a. pair of uprights, cross bars secured thereto having horizontal flanges or webs, upright bars having overturned ends pivoted at top and bottom to the said horizontal flanges of the cross bars, and seat and back supporting arms riveted to said vertical bars, substantially as described.

2. In combination, a pair of standards having upper and lower horizontal flanges, vertical bars having horizontally turned ends, said horizontally turned ends being designed to abut against and be pivotally connected to said horizontal flanges, one of said parts having a plurality of holes, a pivoted pin at each end of said vertical bar passing through one of said plurality of holes and forming an adjustable pivot connection between each horizontal flange and the horizontally turned end of the vertical bar, and seat and back supporting arms riveted to said vertical bar, substantially as described.

In testimony whereof, I affix my signature in presence of two witnesses.

ROBERT W. IRWIN.
